nodeName

public Name nodeName()

Description copied from interface: Item

XDM 3.1 Section 5.10 node-name Accessor. dm:node-name($n as node()) as xs:QName? "The dm:node-name accessor returns the name of the node as an xs:QName, or the empty sequence if the node does not have a name."

Specified by:

nodeName in interface Item

Returns:

the expanded name (Name) of the node, or null when the accessor yields the empty sequence

parent

public Item parent()

Description copied from interface: Item

XDM 3.1 Section 5.11 parent Accessor. dm:parent($n as node()) as node()? "The dm:parent accessor returns the parent of the node, or the empty sequence if the node has no parent."

Specified by:

parent in interface Item

getStringValue

public String getStringValue()

Description copied from interface: Item

Returns the string value of the item, if it is an atomic item.

Specified by:

getStringValue in interface Item

Returns:

the string value.

setParent

public void setParent(Item parent)

Specified by:

setParent in interface Item

getDynamicType

public ItemType getDynamicType()

Description copied from interface: Item

Returns the dynamic type of the item (only for error message purposes).

Specified by:

getDynamicType in interface Item

Returns:

the dynamic type as an item type.

nodeKind

public String nodeKind()

XDM 3.1 Section 6.3 Attribute Node Accessors — node-kind. "For an Attribute Node, dm:node-kind returns the string \"attribute\"."

Specified by:

nodeKind in interface Item

children

public List<Item> children()

XDM 3.1 Section 6.3 Attribute Node Accessors — children. "For an Attribute Node, dm:children returns the empty sequence."

Specified by:

children in interface Item

attributes

public List<Item> attributes()

XDM 3.1 Section 6.3 Attribute Node Accessors — attributes. "For an Attribute Node, dm:attributes returns the empty sequence."

Specified by:

attributes in interface Item

isId

public boolean isId()

XDM 3.1 Section 6.3 Attribute Node Accessors — is-id. "For an Attribute Node, dm:is-id returns true if the attribute node is of type xs:ID or is derived by restriction from xs:ID; otherwise it returns false." RumbleDB does not currently support schema type annotations on attributes, so this implementation always returns false.

Specified by:

isId in interface Item

isIdrefs

public boolean isIdrefs()

XDM 3.1 Section 6.3 Attribute Node Accessors — is-idrefs. "For an Attribute Node, dm:is-idrefs returns true if the attribute node is of type xs:IDREF or xs:IDREFS or is derived by restriction from one of these types; otherwise it returns false." RumbleDB does not currently support schema type annotations on attributes, so this implementation always returns false.

Specified by:

isIdrefs in interface Item

equals

public boolean equals(Object other)

Description copied from interface: Item

Tests for logical equality. The semantics are that of the eq operator.

Specified by:

equals in interface Item

Overrides:

equals in class Object

Parameters:

other - another item.

Returns:

true it is equal to other, false otherwise.

isNode

public boolean isNode()

Description copied from interface: Item

Tests whether the item is an XML node.

Specified by:

isNode in interface Item

Returns:

true if it is an XML node, false otherwise.

isAttributeNode

public boolean isAttributeNode()

Description copied from interface: Item

Tests whether the item is an XML Attribute node.

Specified by:

isAttributeNode in interface Item

Returns:

true if it is an XML Attribute node, false otherwise.

hashCode

public int hashCode()

Description copied from interface: Item

Computes a hash code.

Specified by:

hashCode in interface Item

Overrides:

hashCode in class Object

Returns:

a hash code as an int.

atomizedValue

public List<Item> atomizedValue()

Description copied from interface: Item

XDM 3.1 Section 5.12 string-value Accessor. dm:string-value($n as node()) as xs:string "The dm:string-value accessor returns the string-value of the node as defined for each node kind." In this API, node string values are exposed via getStringValue() and the default implementation of dm:typed-value delegates to atomizedValue().

Specified by:

atomizedValue in interface Item

namespaceNodes

public List<Item> namespaceNodes()

Description copied from interface: Item

XDM 3.1 Section 5.7 namespace-nodes Accessor. dm:namespace-nodes($n as node()) as namespace-node()* "The dm:namespace-nodes accessor returns the dynamic, unordered set of Namespace Nodes. It is defined on all seven node kinds." This default implementation is only a placeholder on the generic Item interface and must be overridden by XML node implementations that support namespaces.

Specified by:

namespaceNodes in interface Item

declaredNamespaceNodes

public List<Item> declaredNamespaceNodes()

Description copied from interface: Item

Helper accessor for XML element nodes: returns namespace nodes for the namespace bindings declared directly on the element. This does not include inherited or statically known namespaces — only the bindings explicitly declared on the element (for example via xmlns attributes). Non-element nodes must override this to return the empty sequence.

Specified by:

declaredNamespaceNodes in interface Item

baseUri

public List<Item> baseUri()

XDM 3.1 Section 6.3 Attribute Node Accessors — base-uri. For an Attribute Node, dm:base-uri returns the base URI of the parent element or document node, if it has one; otherwise it returns the empty sequence.

Specified by:

baseUri in interface Item

documentUri

public List<Item> documentUri()

XDM 3.1 Section 6.3 Attribute Node Accessors — document-uri. For an Attribute Node, dm:document-uri returns the document-uri of the document node that is the root of the tree containing the attribute, if it has one; otherwise it returns the empty sequence.

Specified by:

documentUri in interface Item

nilled

public List<Item> nilled()

XDM 3.1 Section 6.3 Attribute Node Accessors — nilled. For an Attribute Node, dm:nilled returns the empty sequence.

Specified by:

nilled in interface Item

typeName

public List<Item> typeName()

XDM 3.1 Section 6.3 Attribute Node Accessors — type-name. For an Attribute Node, dm:type-name returns the name of the dynamic type of the attribute node, or the empty sequence if the node is untyped. RumbleDB does not currently support schema-validated attribute types, so this implementation returns the empty sequence.

Specified by:

typeName in interface Item
